Abstract

Изобретение относится к способу изготовления полиамидных нановолокон в результате электроформования, который представляет собой способ многосоплового электроформования при использовании многосоплового устройства или бессопловое электроформование при использовании бессоплового устройства, включающему стадии, на которых прикладывают высокое напряжение, полимерный раствор, содержащий полимер и растворитель, подают в многосопловое устройство или бессопловое устройство и преобразуют под действием высокого напряжения в заряженные потоки струй, потоки струй осаждаются на подложке или захватываются коллектором, и полимер в потоках струй затвердевает, образуя в результате нановолокна, причем полимер содержит полукристаллический полиамид, характеризующийся соотношением C/N, равным, самое большее, 5,5, и среднемассовой молекулярной массой (Mw), равной, самое большее, 35000. Изобретение также относится к полиамидным нановолокнам, изготовленным по способу электроформования, а также к продуктам, изготовленным из них, и их применению.The invention relates to a method for manufacturing polyamide nanofibers by electrospinning, which is a multi-nozzle electrospinning method using a multi-nozzle device or nozzleless electrospinning using a nozzleless device, including steps in which a high voltage is applied, a polymer solution containing a polymer and a solvent is fed into a multi-nozzle device or a nozzleless device and converted under high voltage into charged streams of jets, the streams of jets are deposited on a substrate or captured by a collector, and the polymer in the streams of jets solidifies, forming nanofibers as a result, and the polymer contains a semi-crystalline polyamide, characterized by a C/N ratio of at most greater than 5.5 and a weight average molecular weight (Mw) of at most 35,000. The invention also relates to electrospun polyamide nanofibers and products made derived from them, and their application.
